Subject: Kernel splat related to bad rate in latest wireless-testing (3.4.0-rc3-wl+)
Date: Tue, 17 Apr 2012 10:26:10 -0700 [thread overview]
Message-ID: <4F8DA7B2.1060303@candelatech.com> (raw)
This has my ethtool & scan-on-channel patches and Felix's patch to make virtual stations
work on ath9k again.
I had 'reset' a virtual station interface, which basically bounces it and
tells supplication to re-associate.
